WOOD-TRIMMER.

SPECIFICATION forming part of Letters Patent No. 504,209, dated August29, 1893.

Application filed December 21, 1892. Serial llo-455.896. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM R. FOX, a citizen of the United States ofAmerica, residing at Grand Rapids, in the county of Kent and State ofMichigan, have invented certain new and useful Improvements inWood-Trimmers, of which the following is a specification.

My invention has for its object to provide a gage having a Wide range ofadjustment and to provide means for controlling the same in order tomaintain its shearing edge accurately at the line of cut.

It relates also to the particular arrangement of the frame with relationto the gage and knife in Orderthat the gages may be adj usted through awide range and whereby the frame may be provided with shields withoutinter'- fering with the movement of the gages.

The invention includes a pivotal connect-ion between the gage and thebed or frame located below and in the same plane with the line of cut;the special form ofthe connection extending through a slot in the bedand comibined with a clamp also operating through the said slot, andmeans for quickly and accurately setting the gage to any angledetermined upon. A

In the drawngsz-Figure 1, is a rear perspective view of the machine.Fig.' 2,` is a plan, and Fig. 3, a vertical section from front to rearthrough one ofthe gages. Fig. 3a is a detail view of the preferred gagestop. 'Fig'. 4 is a detail bottom plan view of the pivotal connectionfor the gage.

The machine frame includes a bed 1, having a way 2, extending acrossnear the rear face by which the knife carriage 3, is directed so thatthe knives 4, carried thereby will move along the cutting line 5--5. Thecarriage is moved by aweighted lever 6, pivoted to the frame at 8, andhaving a segment 9, meshing with a rack 10, on the carriage. The upperedge of the carriage moves in a Way formed in the cross bar 11,extending between two posts or brackets 12, the lower right angular arms13, of which are bolted to the rear face of the bed or frame and in rearof the plane of the knife carriage and knives. To these brackets theangular wings or shields 14, are secured or cast extending laterally ofthe machine and directly adjacent to the plane which the work is placedwill in one position f be at an angle of forty-five degrees withrelation to the line of cut and in the other extreme position at anangle of thirty degrees the shearing edge being always maintained at thecuttingline. For this purpose a curved slot 18, is formed in the bedplate and into this the arm 19, of a forked bracket 20, ex

tends to connect with the bottom of the gage byvmeans of two screws 21,the end of the bracket arm having abroad bearing and being seated in arecess on the under side of the gage. The arm 22, of the bracket extendshorizontally to the rear and at its rear end an upturned pintle or pivotis formed which fits a bearing socket'-23, on the under side of the bed,the center of which is directly under the line of cut and of theshearing gage edge 16. By this construction theshearing edge will beheld at the cutting line in all the adjustments of the gage and the gagemay be fixed in any position by the clamp consisting of the cap 24,bearing on the under side of the bed along the edges of the slot betweenthe forked arms of the brackets 2Q, and a clamp Vrod 25, having a head26, at its lower end and an eccentric lever26f, pivoted at its upperend. By this construction both the clamping means and the pivotalconnection extend through the slot from the gage. The eccentric lever isarranged over a boss or enlargement 27, between the two wings of thegage.`

In order `that the gage may be set quickly and accurately in anyposition I provide a pin 28, in the boss 29, on the gage which pin ispreferably forced down by a spring 30, to engage with the table thusserving as a stop preferably by entering any one of a series of holes inthe table corresponding to the different angles to which it is necessaryto shift the gage.

The lower end of the pin is conical. As before stated the frame work ofthe machine is in rear of the knife carriage so as to leave the bed freein front of the carriage for the adjustment of the gages. The shields orwings are also in rear of the carriage and by reason of this arrangementthey can be made to veX- tend completely over the side of the knives soas to shield the entire edge thereof when the knife is shifted to oneside. This would not be the case were the wings in front of the plane ofthe knives as it would be necessary then to cnt away a part of theshield to allow the gage to swing its full distance or the adjustnjieitof the gage would have to be more lim- 1 e In Fig. 3 is shown thepreferred manner of Supporting the spring stop for the gage in which theboss 29X is tted to an enlarged opening 40, in the gage which willpermit adjustment of the boss laterally, such adjustment being allowedalso by the enlarged openings 4l, in the flange 42, through which theholding screws 28X pass into the gage.

I claim- 1. In combination, the bed or frame, the knife and carriagewith operating means therefor, the swinging gage, having a shearing edgeat the line of cut and the pivotal connection between the gage and theframe, the center of which is in the plane of the shearing edge andcutting line and below the same, said gage having its bearing faceradiating from the center of the gage pivot, substantially as described.

2. In combination the bed or frame, the knife and carriage withoperating means therefor, the swinging gage havingashearing edge at theline of cut and the pivoted connection between the gage and framecomprising the arm extending from the gage through a slot in the frameand pivoted at its end thereto, the center of the pivot being in theplane of the cutting line and below the same, said gage having a bearingface radiating from the pivot center, substantially as described.

3. In combination, the bed or frame, the knife and carriage withoperating means therefor, the swinging gage havinga shearing edge in theplane of the cutting line and the pivotal connection between the gageand the bed comprising the arm connected to the gage extending under theframe and having an upturned pivot at its end fitted to a socket in theplane of the cuttinglne and shearing edge of the gage, substantially asdescribed.

4c. In combination, the slotted frame, the knife carriage and knife, thegage, the pivotal connection extending therefrom through the slot to theunder side of the frame and the clamp for the gage extending through theSlot and bearing on the edges of the slotted frame independent of thepivot connection, substantially as described.

5. In combination, the slotted frame, the knife, and knife carriage, thegage, the forked bracket extending from its under side through the slotto the lower side of the frame to which it is pivotedand the clamp forthe gage extending between the forks of the bracket, substantially asdescribed.

6. In combination the frame, the knife, the gage having a shearing edgeat the line of cut and the setting stop for the gage consisting of thevertically movable pin on the gage adapted to enter holes in the bed,said stop being adjustable laterally of the gage and longitudinallythereof toward and from the shearing edge, substantially as described.

7. In combination, the gage having the opening, the boss of smallerdiameter adapted to said opening and adapted to be moved laterallytherein in any direction, and having a flange with openings, the screwspassing through said openings and of smaller diameters than saidopenings, and the stop passing through the boss to engage the table orbed, substantially as described.

8. In combination, the frame having the bed, with the holes therein, theknife, the gage having a shearing edge at theline of cut and the settingstop arranged on the gage consisting of the conically pointed,vertically movable pin, said pin being adjustable laterally andlongitudinally of the gage and oper ating to set the gage at the properangle and also to set it in relation to the line of cut,sub stanti-allyas described.

In testimony whereof I affix my signature in presence of two witnesses.

It is hereby oertied that in Letters Patent No. 504,209, granted August29, 1893, upon the application of William R'. Fox, of Grand Rapids,Michigan, for an improve* ment in Wood-Trimmers, an error appears in theprinted speeieation requiring correction, as follows: Page 2, after line24, the paragraph It will be noticed that the stop may he adjusted notonly laterally of the gage but longitudinally thereof or toward or fromthe shearing edge. This latter adjustment is important as the stop isthas made to aet as an adjustable setting de'vice by which the shearingedge may he maintained at the line of cut eren should there he loosenessat the pivot bearing due to wear. should be inserted at the end of theline and that the said Letters Patent should be read with thiscorrection therein that the same may conform to the record of the oasein the Patent Oloe.
